With a process called Fission. This generates heat to produce steam.
Answer:
East
Explanation:
Given Newton's third law of motion; "Action and reaction are equal and opposite", when a student jumps off a sled toward the west after it stops at the bottom of an icy hill, the sled will move in the East direction.
This is because, the force exerted on the sled is a reaction force and is opposite in direction to the force that thrusts the boy westward though equal in magnitude with the former.
Hey there!:
β-decay:
Unstable nucleus undergo β-decay in which a neutron is converted into proton , so
¹₀ n ----> ₁¹p + ₋₁⁰e ( Z + 1 )
The complete reaction is as follows:
²²⁷₈₉AC -----> ²²⁷₉₀ Th + ₋₁⁰e
Therefore , the daughter nucleus is : ²²⁷₉₀ Th
Hope that helps!
Answer:
Explanation:
In this, we can with the <u>ionization equation</u> for the hydrazoic acid (). So:
Now, due to the Ka constant value, we have to use the whole equilibrium because this <u>is not a strong acid</u>. So, we have to write the <u>Ka expression</u>:
For each mol of produced we will have 1 mol of . So, we can use <u>"X" for the unknown</u> values and replace in the Ka equation:
Additionally, we have to keep in mind that is a reagent, this means that we will be <u>consumed</u>. We dont know how much acid would be consumed but we can express a<u> subtraction from the initial value</u>, so:
Finally, we can put the ka value and <u>solve for "X"</u>:
So, we have a concentration of 0.000285 for . With this in mind, we can calculate the <u>pH value</u>:
I hope it helps!
True
Explanation:
Lead is the stable form of uranium 238. Lead-206 is a product of radioactive decay of unstable uranium 238 isotope.
- Atomic nucleus have a specific neutron/proton ratio that ensures their stability.
- Nucleus whose proton/neutron ratio is different from that of its stability ratio will be unstable and split into other nuclei.
- This splitting is accompanied with emission of small particles of matter and or electromagnetic radiation.
- Unstable uranium -238 undergoes 14 radioactive decays to produce a stable form which is Pb-206
